Tiny supercomputer of 1 atom thickness developed

A physicist from Sydney has created a tiny computer of 300 atoms hovering in space.

Quantum computer built within diamond

Researchers have built a quantum computer in a diamond, the first of its kind to include protection against “decoherence” – noise that does not allow the computer to function correctly.

Quantum computer on the anvil?

Today`s computers use binary bits of data that are either ones or zeros. Quantum computers would use quantum bits, or "qubits", which can be both ones and zeros at the same time, thanks to the quirks of quantum mechanics.

Scientists can now control super-fast quantum computer
